FURLONG, OF ROCHESTER, NEW YORK, ASSIGNOR TO THE YAWMAN & EBBE MANUFACTURING COMPANY, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK Application filed June 27,

This invention relates to a support for visible index trays by which the tray may be slid into and out of a cabinet and which shall be so related to the trayas to permit it to be fully occupied by cards without sacrifice of any of its space. More particularly, the invention seeks to provide a sliding support with which the tray itself is telescopically engaged so that the tray may have sliding movement with respect to the support and be drawn into such a position with respect thereto as to expose the tray and its cards for nor mal use. A further object of the invention is to provide means on the tray support for positively lifting the top card from its overlying relation to the index cards when the tray is fully retracted, the top card being returned to its overlying position when the tray and support are returned into the cabinet. A further object of the invention is to provide actuating means for the top card which may be removed from engagement with the coacting means on the tray support so as to permit the tray to be withdrawn bodily from the tray support without further operation. v

The invention will be described in detail in connection with the illustrated embodiment shown in the drawings, wherein:

Figure 1 is a fragmentary View in side elevation of a cabinet showing a tray and improved tray support withdrawn therefrom and the top card elevated by the coacting means.

Figure 2 is a view of a fragment of the tray and support shown in Figure 1, the cabinet being illustrated in horizontal section to show how the tray supportis slidably engaged therewith, the section being taken on the line 22 of Figure 3 and looking in the direction of the arrows. I

Figure 3 is a view in side elevation of the improved tray support and tray, the near wall of the cabinet being broken away in the interest of clearness and the tray being only partly retracted. 1

Figure 4 is a view similar to Figure 3 showin g the tray fully retracted.

gagement therewith of the tray support and i taken on the plane indicated by the line 5-5 V of Figure 4 andlooking in the direction of ing pins 0 carried by the tray support which will be described hereinafter. One or both of the pins 0 as shown at the right-hand side of Figure 2 may be retractible for disengagementwith the ways I) of the cabinet so that the tray support may be demounted. A finger pull 0' at the inner end of the pin 0 facilitates its convenient operation. The tray support is of simple and inexpensive construction when made in accordance with the illustrated embodiment and may comprise a false tray having a transverse" bottom 1 and channeled flanges 01' along its opposite side edges. These channel flanges are of such shape and dimensions as to receive slid ably therein the card tray 6 so that the card tray is in sliding and telescopic relation to the tray support 03. So far as the construction has been described it willbe apparent that with any suitable means toprevent the tray 6 from being wholly withdrawn from the tray support (5 when drawn out of the cabinet a simple and inexpensive tray support is aiforded whereby the tray may be slid into the cabinet through the sliding engagement of the pins 0 with the ways I).

In accordance with the further object of the invention a simple and effective. stop for j the tray is provided to prevent its complete withdrawal while atthe sametime permitting the tray, to be used in its full length i wit-h the usual index cards therein and without requiring any standard type of tray to be modified in construction. At the inner end of the tray'there is provided as usual a pivotal support for a top card 7, the pintle therefor being indicated at f. Spaced from the pintle f and carried on the top card f are outwardly extending pins f which in the illustrated embodiment are made as independent sections normally 'u'rged into their extended position by a spring 9 operatively together with the slidable tray support 03.

pieces f so that the ends of the pins will clear interposed between the proximate ends thereof. Each of the pins f may be formed with a finger piece f whereby they may conveniently be retracted against the pressure of the spring 9 for the purpose to be pointed out hereinafter,

On the channeled flanges (Z' of the tray support (Z are secured cam stops it preferably provided with inclined cam surfaces It engageable by the pins f when the tray is drawn outwardly, these cam surfaces ter minating preferably in vertically disposed edges k which serve as positive stops for the pins f preventing their further travel with respect to the tray support (Z.

From the description given it will be ap parent with reference to Figures 3 and lthat when the tray is grasped by the usual finger pull 6 it will be withdrawn from the cabinet WVhen the pins 0 of the tray support reach the forward ends of the ways 6 further .movement will be positively checked by engagement with the cabinet. Continued movement of the tray 0 in the channel flanges all will bring the pins fof the top card f into engagement with the cam surfaces h of the stops it. As the pins 7" ride up these cam surfaces it will be evident that the top I I card will be swung upwardly about the pintle f until the pins f engage the vertical stops k at which time further movement of the tray 6 and the top card f with respect to the traysupport (Z is positively arrested. At this time, as shown in Figure 3, the top card has been swung away from the index cards which it normally overlies and the full length of the tray is exposed to view for manipulation of the cards therein. The tray with the tray support may be dropped to an angular position moving about the pins 0.

If it is desired to remove the tray from the card support or to engage a tray therewith the pins f can be retracted against the action the cam stops it and thetray e by reason of its telescopic engagement with the support cl can be pulled out until it is disengaged therefrom.

' to assemble and disassemble, permits the introduction or removal of the tray supports from a cabinet andpermits the introduction or removal of trays from the tray supports. Details of construction by which equivalent results are obtained may be changed readily as will be apparent to any skilled mechanic without departing from the spirit of the invention.

What I claim is:

l. A supportfor a visible index tray comprising a unitary member having channels to receive the tray slida-bly and telescopical- 1y, a top card hinged to the tray,'a cam stop carried by the support and means on the top card to engage the cam stop when the tray is moved in one direction with respect to the support whereby the top card is swung upwardly and further relative movement of the tray and support positively checked.

2. A support for a visible index tray comprising a member having means to receive a tray telescopically and slidably, a top card hinged on the tray, pins carried by the top card spaced from the hinged support thereforand overlying the'tray support, cam stops carried by the tray support and engageable by said pins upon movement of the tray with respect to the support, whereby the top card is swung upwardly and further movement of the tray positively arrested.

8. A support for a visible indextray comprising a member having means to receive a traytelescopically and slidably, a top card hinged on the tray, pins carried by the top card spaced from the hinged support therefor and overlying the tray support, cam stops carried by the tray supportand engageable by saidpins upon movement of the tray with respect to the support,.whereby the top card is swung upwardly and further movement of the tray positively arrested, and means to retract said pins from the path of the cam stops. 7 Y

4. In combination with a cabinet having opposed ways, a support for a visible index tray comprising a unitary false tray section having channels at its opposite edges to receive a tray in telescopic sliding relationship thereto, means carried with the false tray section in sliding engagement with the ways to support it in the cabinet, said means constituting a pivotal connection whereby when the false tray section is retracted from the cabinet it may beswung downwardly from the horizontal, and coacting means carried by the false tray section and the tray to limit relative sliding movement therebetween, whereby the channels hold the tray against relative angular movement with respect to the false tray section.
